AKM, producer of the DAC and support chips many of us use, burned to the ground a few days ago. This eliminates product from them for six months to a year.
Luckily we had a bit of inventory and found an additional supply on the web, but at about twenty times the normal price. This will keep us going for a while, but we will need to raise our DAC price by about $150 to cover the extra cost.
We can build five more before the price goes up.
